Procedure

To a solution of 1-bromo-3-chloropropane (3.4 mL, 34.5 mmol) in DMF (40 mL), was added potassium carbonate (6.4 g, 69 mmol) and morpholine (2.0 mL, 23.0 mmol). The solution was stirred at RT for 15 h, then diluted with H2O (150 mL). The mixture was extracted with EtOAc (3×25 mL) and the organic extracts were washed with H2O and brine. The organic phase was dried over MgSO4, filtered, and concentrated in vacuo to give title compound as a colorless oil. MS (ESI, pos. ion) m/z: 164 (M+1). Mass Calc'd for C7H14ClNO: 163.08.
